ELECTRIC RAZOR.` L

'Application sled April 13,

This invention relates to new and useful improvements in electricrazors.

The object ot the invention is to provide a razor of the vibratorytypepossessing certain highly advantageous and improved features, making fora more satisfactory andeficient device. Y

A particular object of the invention is to provide means for minutelyregulating the amplitude of the reciprocation of the blade.

An important object of the invention is to provide a simpleand practicalmeans of fastening the blade to the carrier posts; whereby it may bequickly and easily placed or removed-and whereby it will be lirmly andproperly held in working relation to the guard'teeth.

Another object of the invention is to provide a simple forni of solenoidand a novel means of adjustable connection between the core and thepitman, whereby the vibratory -action'may be controlled.

A construction designed to carry out the invention will be'v hereinafterdescribed together with other features ofthe invention.

The invention will be more readily understood from a reading of thefollowing speciication and by reference to the accompanying drawings, inwhich an example of the invention is shown, and wherein: y

Fig. 2 is a front elevation of the same,

Fig. 5 is an end elevation of the razor,

Fig. 6 is an enlarged cross-sectional view on the line 6-6 of Fig. 4,

Fig. 7 is an enlarged cross-sectional view taken on the line 7-7 of Fig.4,

Fig. 8 is a detail ot the blade latehing post connection.

1n the drawings the numerall() designates an elongated head having atlat tace 11 provided with a central recess 12. Along the side edges otthe head contiguous to the face guard teeth 13 are provided. Thehead isintegral with and olset laterally from a short neck 14 disposedcentrally of a cap 15. The oap 15 has a screw threaded flange 16engaging in the internally screw threaded end of a cylindrical handle17.

The neck and cap have an axial bore 18. The head is formed on its rearside with By pressing 1925. Serial No. 22,806.

spaced bearing brackets 19. A cylindrical carriage 2O is mounted toslide in thebores of these brackets, which bores are preferablyconcentric to the bore 18. The carriage has a shoulder 21 below thelower bracket 19 and is secured at this point to a pitman 22 extendingthrough thebore 18. A coiled spring 23 surrounding the pitman is seatedin arecess 24 in the neck and hasits upper end en- "gaging around theshoulder.

A keeper post 25 extends through a slot 26 in the head and has itsreduced screw threaded end 27 engaged in the carriage 20. A latchingpost 28 extends through a slot 29 in the head and a slot 30 in thecarnage and has its reduced screw'threaded end 31 en-I gaged in aplunger 32 slidable in a counterbore 33 in the end of said carriage. Theplunger has a head 34 on its end extending from the carriage; while itsinner end compresses a coiled spring 35 confined in the bore 33. a

Each post has an angular collar 36 integral therewith and resting on thebottom of the recess 12. Outwardly of the collar each post has arounded'head 37 and between the collar and the head, an annular groove38.

plunger 32, the latter is depressed against the tension of the spring 35and the post 38 is moved in its slots 29vand 30 toward the post 25. Bythis arrangement a double edge blade 39 having a central longitudinalslot 40 may be engaged over vthe heads 37 and inwardly'onY the head 34of the supported on the collars 36. When pressure on the plungerisreleased the post 28 is displaced, whereby the blade is pulled intothe groove 38 by the keeper post 25 and is received in the groove 38 ofthe latching post 28; thus being securely and lirmly held upon thecollars. The grooves 38 are ot' course very shallow.

The blade is supported on the tace 11 at each side ot the recess 12 sothat its cutting edges overhang the guard 'teeth 13, but may be carriedentirely upon the collars 36 and spaced a fraction of an inch from theface. ln order that the vibratory or reciprocative movement of thecarriage 20 may be controlled, l'provide a conical sump carriagefor'receiving the conical end of a regulating screw 42 (Figs. 3 and 4)mounted in the head. In the sump 41 is mounted a bushing 4V of libre orany other material suitable for the purpose of eliminating noise whenthe end of the screw contacts there;

41 in the with during the reciprocation of the carriage. By adjustingthis screw into and out of the sump the space between the sides of theconical end and the walls of the sumps is varied and the travel of thecarrier 20 is either shortened -or lengthened. This is a Very importantfeature because it assures a uniform travel of the blade and controlsthe spring action as well as the amplitude of the magnetic action.

In the handle I mount a solenoid 43 havin a central Well 44 in which acore 45 is sli able. The solenoid is confined by a disk 46 of electricalinsulating material which receives the collar 16. The solenoid passessnugly screw threaded end of the pitman 22. lock nut 47 mounted on saidthreaded end binds upon the end of the core and fastens the core againstrotation. By this means the core may be adjusted so as to properlyfunction when the solenoid is energized.

The solenoid rests upon an insulating disk 48 supported upon a shoulder19 atthe reduced lower end of the handle 17. The solenoid has terminalposts 49 (Fig. 2) depending through the disk and entering an attachmentplug 50 which is inserted in the lower end of the handle. An electriccurrent cord 51 is connected to the plug for supplying current to themagnet. The handle 17 is preferably'formed of hard rubber or any othernon-conductive material.

In using the razor the operator grasps the handle 17 and turns on theelectrical current. Thus causes the solenoid 43 to bc energized so thatit attracts the core 45 and pulls the same downwardly. The solenoidillustrated is designed to be used with alternating current andtherefore when the core has been pulled down it will be momentarilyreleased, due to the pulsations of the current thereby permitting thespring 23, which was compressed on the down stroke, to expand and returnthe carriage. By this arrangement the stroke of the carriage will beeffected in one direction by the solenoid and in the other direction bythe spring. As the pulsations are rapid, so will the reciprocatlon ofthe carriage and blade be.

' The throw of the carriage can be minutely controlled by the screw 42and in actual practice, not over a of an inch is required, although thisis subject to variation. The blade may be quickly released 'andIreplaced by simply depressing the plunger 32 and lifting the blade orlaying it upon the collars 36. rIhe whole device is comparatively lightin weight and may be readily cleansed. The slots 26 and 29 aresuiiiciently long to prevent contact ywith their ends by the posts andthis obviates noise.
